Here is some text from the GNU make manual.

"Except by explicit request, make exports a variable only if it is
either defined in the environment initially or set on the
command line, and if its name consists only of letters, numbers, and
underscores. Some shells cannot cope with
environment variable names consisting of characters other than
letters, numbers, and underscores.

The special variables SHELL and MAKEFLAGS are always exported (unless
you unexport them). MAKEFILES is exported if you set
it to anything.

make automatically passes down variable values that were defined on
the command line, by putting them in the MAKEFLAGS

I don't see evidence that srcdir will normally be available in
libtool's environment.
